Abstract
Glass fibers prepared by flame attenuation display excellent chemical resistance to both acids and moisture while being highly biosoluble at the same time. The glass compositions are characterized by ratios of components which are reflective of acid resistance, biosolubility, and moisture resistance. Preferred glass fibers exhibit a biodissolution greater than about 350 ng/cm/2hr.
